I want to set a random seed for a random number generator. I tried
this:
getSeed = do
time <- getClockTime
return (ctPicosec (toUTCTime time))
seed <- getSeed
randList minval maxval = randomRs (minval,maxval) (mkStdGen seed)
But I get the error: parse error on input `<-' which refers to
"seed<-getSeed".
Using "seed<-getSeed" from the ghci command line works. Why doesn't
it work in a
script?
THe second problem is the seed is of type Integer but mkStdGen wants
an Int. How can I get an Int from an Integer? I tried mod to get the
seed to within range for an int but the result is still of type
Integer how can I coerce Integer to Int when I know result will fit?
Thanks
